IMPROVEMENT IN APPARATUS FOR DRVING AND FINISHING PAPER.

Specification forming part of Letters Patent No. 120,810, dated November14, 1871; antedated October 26, 1871.

To all whom it may concern:

Be it known that I, HEZEKIAH DODGE, of Albany, in the county of Albanyand State of New York, have invented an Improvement in Machines forDrying and Finishing' Paper or other material, of which thefollowing isa specification:

My invention relates to the drying of strips or pieces of paper, cloth,or other material by passing them between flat stationary heatedsurfaces, (the upper and under surfaces of metallic chests or boxes,hereafter shown,) the strip or piece being drawn through and betweenthem under a proper degree of pressure; the material 'being drawnthrough by means of and between two bands of endless tape or felt, orotherwise, and the drying-chests heated by steam.

In the accompanying drawing, Figure'l is a side View of such machine,Fig. 2 an end View of the same.

A and A are the metallic drying-chests, having smooth horizontalsurfaces, between which the material to be dried or nished is carried orv drawn under greater or less pressure, according to the iinish desired.B in the drawing represeuts the steam-supply pipe, through which themetallic drying-chests are supplied with steam and heated. The steam issupplied at the side or bottom or elsewhere, as may be found mostconvenient. The arrow indicates the direction in which the material issupplied to the driers and the opening between the surfaces. More driersor drying-chests may be added above any pair of driers, when required,and the hitherto unused surface G then becomes the under surface of anew drier, operated in the saine manner as the rst. The principle may beincreased ad fmjtwitum.

In this invention the driers are stationary, and the material is drawnthrough and between them, being pressed and heated during its passage,and thus dried.

I claim as my invention- Y The stationary drying-chests A A or otherequivalent, substantially as described, and for the purposeshereinbefore mentioned.

HEZEKIAH DODGE.
